Hey Elcid thank so much!
I ran your the Arctan, and Magnification x 6 methods and recorded the results in the link below. I found your first Arctan ranging method did not work for me and your Mag x 6 fell just short so I changed it to x7 instead and that worked great out to ranges up to 3,000m after that there is a degree of error that gets larger, the further away but that is not important anyhow as you would not be firing torpedoes at that range! ((Mast Height (m) / mils observed) x 7 (Mag) * 1,000) = Range (m) approximate) See here for the video:

Glad I could help! We could use this over with the WW I Kaiser mod since it means you're using simple math for targeting.
I've found a way to verify zoom levels. You have to check a "camera.dat" file for optics in the UZO as well as the two periscopes. I believe they are 7x for the UZO and 1.5x/6x for the two scopes, but I have to download something called S3D to read the thing, though. Need to find it here somewhere. If it's 6x for the scopes, then I would use a factor of 6 for them and not 7 -- even if the answer is a little off. Remember, the max range of a WW I torpedo was about 1500 meters at most (until the end of the war, anyway). These methods were probably taken from the WW I experience, so it wouldn't be surprising that the acuracy drops at longer ranges. I'll check the file unless someone who knows how to use the S3D beats me to it. If verified 6x and 1.5x, then the formula can be updated: For 1.5x ====== ((Height (m) / mils observed) * 1500) = Estimated Range (m) For 6x: ===== ((Height (m) / mils observed) * 6000) = Estimated Range (m) For 7x (UZO only): ============== ((Height (m) / mils observed) * 7000) = Estimated Range (m) For scopes with "5" and "10" instead of the 50/100 marks, just adjust the last value to move the decimal point as needed. Glad this helped! ElCid97 |

Got the S3D thing to work last night.
Checked the "cameras.dat" file that came with KSD2 and can confirm that the UZO is at 7x and the two periscopes are at 6x in the file. The binoculars are set to 10.7x for the zoom. For now multiply the UZO readings by 1500 (with the 50/100 graduations of the mils) and the scopes by 6000 and you should be fine. I'm not sure what the newer SH3 releases use, but I'm inclined to guess they should be the same (1.5x and 6x). You would have to check with OneAlex and the folks at LSH3. The main difference I've seen in videos with regards to those mods for SH3 is that the mils are 5 and 10 instead of 50 and 100 like with KSD2. If the mils are 5/10 on the scope, just multiply by 150 and 600 instead of 1500 and 6000 to get the estimated range in meters. Hope I've been able to help! ElCid97 |
